IMPRQVEMENT IN LAMP=SHAE $L PPRTER$.

Specification forming part of Letters Patent No. 115,527, dated May 30,1871.

To all whom it may concern:

Be it known that I, EDWIN RUSSELL, of YVaterbury,.in the countyof NewHaven and State of Connecticut, have invented a new and ImprovedLamp-Shade Supporter; and 1 do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawing forming part of this specification.

This invention consists in the attachment of the supporting-arm oftheshade-holder to the lamp-collar by means of a ring-clamp provided onthe said arm, and a clamping-screw passing through a slotted portion ofthe said arm for the purpose of tightening the ring upon thelamp-collar.

Figure 1 is a side elevation of a lamp-reservoir with my improvedshade-supporter attached to its collar, the supporting-arm and itsclamping-ring being in section. Fig. 2 is a plan of the lamp-reservoirand the attached s upportin g-arm.

A is the shade-holder,consisting of a ring of metal grooved all aroundits upper face for the reception of the lower edge of the shade. B isthe vertical rod or stem attach ed rigidly to the ring, and having itsattachment stren gthened by oblique braces a. 0 is the supportingarmattached to the exterior of the collar D, which is ordinarily providedon the top of the reservoir E- for the reception of the burner.

This arm is provided at its outer end with a vertical socket, I),through which the rod or stem passes freely, and it has screwed into ita set'screw, c, which, being screwed up tightly against the rod or stemB, secures it at any height to which it may be adjusted in the socket1), according to the desired height of the shade above the lamp. Thisarm is of suitable length to bring the shade-holder A to a positionconcentric with the lamp-collar. The supporting-arm (J is made in thesame piece with a ring, 01, of a size, in its normal condition, to slipeasily over the lamp-collar; and from the interior of this ring a slot,e, extends the greater portion of the length of the arm. Through thisslotted portion of the arm, near the ring, is inserted a set-screw, f,which passes loosely through the portion of the arm on one side of theslot, and screws into a tapped hole in the portion of the arm on theother side of the slot.

By screwing up this screw, after the ring is placed over thelamp-collar, the portions of the arm on opposite sides of the slot aredrawn toward each other, and the ring is contracted upon and made toclamp so tightly the lam pcollar as to secure the arm rigidly thereto,and so form a rigid and firm support for the shade-holder.

What I claim as my invention, and desire to secure by Letters Patent,is-

The arrangement of the ring 61, having a slotted arm, 0, andtension-screw f, socket b, and set-screw c, for supporting ashade-holder by attachment to the lamp-collar D, substantially as shownand described.
